XKT 系列提升机的调绳装置系使用油压推动的齿轮离合器,对比老系列绞车,该装置具有调绳迅速、省力等特点。但是,由于这种提升机没有定车装置,因而打开离合器后,活动绳筒完全靠盘形闸制动器控制。如在调绳过程中,由于误操作或其它原因使带五通阀的电磁铁 G_1断电时,则压力油即可能使盘形闸制动器松开,从而使活动绳筒失去控制而导致严重的提升事故。 XKT series hoist rope adjustment device is the use of hydraulic driven gear clutch, compared to the old series of winches, the device has adjustable rope speed, effort and so on. However, since this type of hoisting machine does not have a stop device, when the clutch is opened, the movable cord reel is completely controlled by the disc brake. Such as in the process of adjusting the rope, due to misoperation or other reasons with a five-way valve solenoid G_1 power, the pressure oil that may make disc brake brake release, so that the loss of control of the active rope and lead to serious Improve the accident.
